I have a new customer who wants to try the wormer.
He asked how often he should use it to begin with.
He has 25 horses, so would be very costly to have fecal checks on all of them.
He wondered if he should worm them again in 2-3 mos.
Thanks for your help.
It would be far LESS costly to do fecals because MOST Likely, few would have worms. Worms are and individual rather than a herd situation based on immunity and resistance. I never suggest a calendar deworming… not even with chemicals. Way to many resistant strains from such practices already.
